BOILER-CLEANER.

SPECIFICATION forming part `of Letters Patent No; 647,409, dated .April 10, 1900.

Application filed December 20, 1899. Serial No. 741,017. (No model.)

T0 alt whom it may concern: Y

Beit known that we, FRED A. HUDSON and HENRY A. ALLISON, citizens of the United States, residingat Cedar Falls, in the county of Black Hawk and State of Iowa, have invented certain new and useful Improvements in Boiler-Cleaners; and we do `declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This inventionrrelates to new and useful improvements in boiler-cleaning receptacles, and particularly to a device which is cylindrical in form and perforated and containing a series of disks which are held to the heads of the receptacle by means of wires, whereby the disks may be easily adjusted in place and removed when it is desired to fill the recep-A tacle with such electrolytes as may be found to coact with the metal of which the receptacle and disks and connections are made to produce an electrochemical action for the pu rpose of loosening the boiler-scale.

To these ends and to such others as the invention may pertain the same consists, further, in the novel construction, combination, and arrangement of parts, as will be hereinafter more fully described, and then specifically deiined in the accompanying drawings.

Our invention is clearly illustrated in the accompanyingdrawings, which, with the letters of reference marked thereon, form a part of this application, and Vin which drawings- Figure l is a side elevationnof our boilercleaning receptacle. Fig. 2 is a central longitudinal section through the receptacle. Fig. 3 is a cross-sectional View through the receptacle, and Fig. `is an enlarged` etail view in perspective of one of the disks.

Reference now being had to the details of the drawings by letter, A designates the cylindrical portion of the receptacle, which is made, preferably, of zinc or any other material which may be found to be adapted for the The circumference of said cylindrical portion is perforated, as shown. The

ends B of the receptacle. are perforated and have wings bent at right angles and adapted to fit insideof the bore of the cylinder, and the diameter of each cylinder-head is greater than the diameter of the cylindrical portion of the receptacle for the purpose of supporting the cylindrical portion a slight distance above the surface of the boiler on which the receptacle is adapted to rest,whereby the perforations are kept open.

Mounted on a longitudinally-disposed wire C, which wire is preferably made of copper,

lare the disks D, made of zinc, said disks being slitted and having two oppositely-disposed wings bent at right angles to the remaining wings, which are parallel to the cylinder ends. Said wires are passed through apertures in the disks and the wings, which are bent at right angles to the ends of the cylinder, are designed-to separate the disks and hold same at given distances apart, as shown in the drawings. On the outer face of each of the cylinder-heads is a disk E, bent as are the disks which are held together by said wire,and passing over two of the oppositely-disposed wings of said outside disk E is a wire which passes through apertures in the heads of the cylinder, in the opposite ends of the latter. Each head of the cylinder has a disk E, bent as described, and which are for the purpose of pre- Venting the receptacle proper from contacting with the inner surface of the cylinder. The ends of the wire being disengaged from the cylinder-head allows the disks within the receptacle to be easily removed when it is desired to place the electrolytes within the receptacle.

In practice it is our purpose to place any suitable electrolytes in the cylindrical receptacle lbetween the disks,which are made, preferably, of zinc held together with a copper wire, whereby an electrochemical action may be produced which will so act upon the boilerscale as .to loosen same from the surface of the boiler. The present application, however, relates merely to the mechanical construction of the receptacle.

What we claim is- A boiler-cleaning receptacle, comprising a cylindrical casing perforated circumferentially, and having open ends, detachable perforated heads of larger diameter than the diameter of thecylinder, integral lugs on said heads adapted to extend within the cylinder,
